Granit starting the long delivery trip to Norway from the Tersan yard in Turkey

Norwegian fishing company Halstensen Granit has taken delivery of its new factory trawler, the 81.20 by 16.60 metre Granit, built at the Tersan Shipyard in Turkey and is a ST-117L design by Norwegian naval architect Skipsteknisk.

The largest vessel of its kind in the Norwegian fleet, Granit is designed for to have a range of sophisticated processing options on board, with a factory deck fitted out with Breivik S424 and 415 heading machines, Baader 190 and Velfag M700 filleting machines and Breivik 51 and Velfag M800 skinning machines, as well as a Valka cutting and portioning machine. The factory deck’s scales and weighing systems are from Marel and Optimar. Optimar and Intech provided Granit’s shrimp processing factory and the two automatic horizontal plate freezers are from Optimar. There are also four vertical plate freezers on Granit’s factory deck.

Granit’s factory deck has a throughput capacity of 90 tonnes per 24 hours and the cargo hold has a 1350m3 capacity. Haarslev supplied Granit’s fishmeal plant, which ensures that all of the factory excess from fillet production is routes to producing high quality fishmeal and oil.

Norwegian environmental institution Enova has played a part in Granit’s development, putting investment into  systems designed to route excess heat to the processing systems on board, and in the Rolls-Royce winch system designed to save energy while also allowing Granit to operate under more difficult conditions than would otherwise be possible.

Granit’s owners went to Wärtsilä for the new trawler’s propulsion, opting for a 6960kW 12V32 main engine as well as the two-speed gearbox, controllable pitch propeller (CPP), the HP nozzle, seals and bearings. Wärtsilä’s two-speed gearbox enables lower propeller speeds and optimised propulsion efficiency, while still using the main engine power for the 3500kW shaft alternator.

The link with Wärtsilä goes back a long way, as the company has previously supplied three pelagic vessels operated by the Halstensen group with propulsion systems.

Additonal power requirements are met by the pair of 1180kW Yanmar gensets and the 147kW Lindenberg emergency set. Brunvoll supplied the 750Kw bow and the 450kW stern thruster.
